b.Specific formulation of learning outcomes
At the end of the course ( 2.5 ECTS) and practical work ( 2.5 ECTS) , students will be able to: - understand and discuss, in a changing environmental context, the issues of water management at different spatial scales ; - describe the processes involved in the different terms of the water balance at the scale of the field parcel and the watershed ; - develop and interpret the equations that are used for describing these processes; - describe working principles of hydrometrological instruments, including the advantages and disadvantages of different instrumentation and monitoring techniques ; - interpret hydrological measurement data (rainfall , evapotranspiration, drainage, runoff) ; - use various hydrological models to calculate various terms of the water balance at the field parcel and watershed scale, with particular attention to the rainfall-runoff relationship in watersheds ; - propose and justify the choice of hydraulic infrastructure to regulate water flow at the catchment basin; - write a report on the practical work and critically analyze the results. |

Practical work
The theoretical aspects are illustrated by practical work in the computer room :
- Geographical characterization of a watershed ( boundary, topographical features) using GIS tools.
- Characterization of rain : time series analysis, IDF diagrams, Thiessen polygon interpolation.
- Modelling evapotranspiration : Analysis of meteorological data, estimation of evapotranspiration by the Penman-Monteith method.
- Modelling of drainage of a field parcel and closing the water balance of the field parcel;
- Modelling the rainfall-runoff relationship in watershed scale: Statistical modeling statistics, conceptual modeling , modeling with a spatially distributed hydrological model ;
- Design of a storm basin.
Two excursions allow illustrating course concepts in a regional setting
- Videos are used to illustrate some aspects of the course, in particular in relation to the section on infiltration and hydrologic modeling
- Practical work in the computer room allow students to use advanced methods of hydrological analysis of field parcels and watersheds.
- The practical work is a executed in a team.
- A written report stimulates the communication skills of the student and allows evaluating the practical work;
- The excursions allows illustrating the concepts of flood control and water conservation in the region.
Evaluation of the written report of the practical work and the excursion.
